To all whom. it may cof/wem.'

Be it known that HENRY R. Gnoviin and ViLrERD J. Gnovsn, both citizens of the United States, residing at McHenry, in the county of McHenry and State of Illinois, have invented certain new and useful Improvements in Sanitary Milking-Fail Covers, of which the following is a. specification.

The present invention relates to dairy devices, and more particularly to milking pails and the like.

An object ofthe present invention is to provide a cover which may be easily applied to the standard milking pail and which is adapted to not only protect the milk in the pail, but to also strain or filter the milk as it enters the pail, so as to exclude and separate out of the milk all foreign matter which may be collected in the milk and from about the pail.

Among the objects of the present invention are to provide a cover which will prevent the spattering of the milk entering the pail, which when applied to the pail will not extend to any appreciable distance above it so that the pail may be handled and used in the ordinary manner, which has its screens or filters so arranged lin the cover that they do not project to any appreciable distance into the pail and thus permit the use of the pail for a relatively large quantity of milk, to provide an attachment for a pail in the form of a cover which contains all of the necessary parts to enclose the pail and screen or filter the milk as it is delivered to the pail, and to provide a device of relatively few parts to which access may be easily gained for cleansing and the like.

A further object of the invention is to provide a milking pail cover with an inlet structure embodying screens and traps, so arranged that foreign matter carried in the milk will be trapped in such a manner that the milk itself will immediately pass from it so as to prevent the soaking of the foreign mattei' in the milk such as is frequently the case with present used devices, and to pi'ovide an arrangement whereby the milk immediately leaves the dirt or other foreign niatter,'so that the latter' may be easily collected from the traps and Ascreens from time to time. Y

Yr'ith the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto. in the drawings, wherein like symbols refer to likeor corresponding parts throughout the several views, j i

Figure 1 is a side elevation of' a milking pail cover constructed according tothe present invention and as applied to the standard pail. 'j

Figure 2 is a vertical section taken through the same substantially on the line 2 2 ofFigurel 1. v j l Figure Bis an enlarged .fragmentary view through a portion of the cover showing the improved inlet in side elevation. Figure t is'a detailtop 'plan view ofthe conical trapjmeinber used showingthe ar.- rangemen't of the spaced screens in theconical bottom.v

Figure 5 is an enlarged vertical section.

taken through one edge of the cover and the pail, the section being `taken Vadjacent to one of the ears of the pail,` andv Figure 6 is a fragmentary outer side elevation of the saine. Y

Referring to the drawings 10, designates a pail of standard construction lwhich isV Yprovided with the usualbead or rolled upper edge 11, upstanding'ears 12 at opposite sides, and a bail or handle 13 of any ap;- proved type which is hinged upon the ears 12. This construction of pail is of course by way of illustration only, asrthe improved cover may be modified within the limits of this invention to adapt it for application `to receptacles of any desired size and conguration. ,Y

The cover comprises a substantially coni"- cal body 14 which is adapted to extend over the upper open end ofthe pail 10 and close it. The body 1st maybe provided atj'its outer marginal edge with an annularI depending flange 15 rolled or otherwise suitably reinforced at its edge and adapted to engage snugly over the bead'11 of the pail.

As shown inFigures 5 and G this depending flange 15 may be provided'with bayonet slots 16 which are cut upwardly throughits rolled edge and which extend circumferentially in one direction and to Ian extent sufficient to receive an adjacent ear 12, the ear 12 serving asv a keeper orlocking member with which the flange 15 may interlock. .in this manner vthe cover 14 is held from accidental displacement frommthetop .of the A pail 10.

The body 14 of the cover is relatively low, so as notto ,project above the top ofthe pailflO any further than is absolutely neces-- sary for accommodating the improved inlet and to holdthe llatter `from projecting vdown4 into the pail 10. The cover or body 14: is provided preferably at one side of its apex With a strap handle 17 of metal or the like which is adapted for use in positioning and removing the .cover \vith respect to the pail. Within the Vopposite side of the cover le the improved inlet is positioned,` the same comprising Aa liXed neck v18 .of frusto-conical forml soldered or otherwise suitably secured to thecoverlt forholding the neck 18 pernianently Lin position. The neck 18 projects but slightly above the cover 14, a distance sufficient only to'receive the upper partof a funnelpiece 19 which is also of Y' frus'to. :o nical ,construction but which is provided at its router edgey With an outturned flange 20Madapted.toengageand seat upon theouterendwof theneck 18. f

The funnelfpiec'e Y19 is provided at its lower end withascreen or`filter21 secured entirelyacross v the inner end vof the funnel piece 19and Vforming the first screen or filter ofthe inlet. The neck 18 carries a conical trap `member22 whichis of cup shape having lits outer tvall'flaringto substantially conform-to the'conical Wall of the neck 18 and Which is adapted to .upon the vinner end of the neck 18j andbind thereon asy the4 Vcup 22 is forced upwardly on'the neck. The conical bottom y 23,projects kinwardly into the cup andconsequently Vrises into the neck 18 to a distance which ,is determined by the slip engagementof the trap member 22 upon the lower en d of theneck. The conical trap member 22 is provided at spaced intervals jin the `conicaldoettom- 23 Withscreens or filters 24 Awhich are not yonlyspaced apart from each other as shoWn'in Figure 4, but

which are also spaced from the marginal edgeof 4thegbottom 2 3 to form between the screens 24 Yand the Wall of the member22 traps or d a1ns a dapted vtocollect and retain foreignmsubstances, particles and .the like which maybe carried through thescreen 21 into the trap member.

A. botto'm` screen 25 having a frusto-conical AWall, is fitted over the ,conical trap Zmember 2 2'and isof greater vheight than thetra-p member and so proportioned asfto provide' an ,inner 'part which istspaced considerably lfrom thebottomv 23 to carry screen bottom 26 forming the final screen orfilter of the inlet.

This screen bottom 26 extends yentirely across the .inner end ofthe `vWall 25 soas to prevent'the trappingof luidwithin the final screen. The Vscreen Wall 25 projects up- Wardly beyondthe conical trap member 22 and is provided in `its upper edge as best seen in Figure' 3 with abayonet slot 27 adapted to engage a pin 28 projecting from lease the final trap lonly from Athe neck vwhen it may be Withdrawn together' With the conical trap member. rlfhe funnel p iece 19 may ofcourse be lifted out of the top of the neck y181at any timefor the removal of sediment Vor the like collected vupon the first screen 21. It is yapparent tliatthe relatively fewrparts are closely nested together in one side of the cover 14, so that the parts do not project` above Yor below the coverto any appreciable extent, .and .consequently the i pail Y1 0 having its cover applied thereto may beliandledand .used in the Ordinary-:manner @tesina the open pail, and the inlet `doesnot ycome incontact withthe milkfin the pail n nderprdinary conditions soy that the pail .may v be Well Afilled Withvmilk and it is nnnecessaryr to frequently empty the palllwaccount of the. dipping ofthe inlet into the milk.

The bayonet slots ..16 in the opposite vvsides of the cover flange 15 may; be quickly inter- Vlocked With theears 12 of the pail byaslight turningof the coverfll onl theV pail after Ythe covenis positioned.I j Theears .12 are therefore utilized for holding the; cover 5from beingknockedoff of the pail should theA pail 1 `Wardly -tapering neck carried by the cover in one side thereof, a funnel piecev fitting in the top of the neck and having a screen in its bottom, a` trap member fitting overthe inner end ofthe neck at A the inner side of the cover, and a second screen meinbeiengaging. over said trap member-andthe innerend ofsaid neck.

A. milking pail cover comprising a `bodyfportion adapted to be placedupon the upperendof a. pail for closingrthesame, a neck carried by the body portionandtprojecting` theretlnough, a funnel piece removably fitting` in the outer lend ofthe neck for vreceiving milk y,andhaving va ,screen bottom, a conical trap member removably fitting .up-

on the inner end of the neck andhaving spaced screens in its bottom for filtering milk therethrough and providing traps between the screens, and a final screen member removably fitting over the conical trap member and upon the inner end of the neck for holding the trap member to the neck.

3. A cover for use upon the upper end of a milking pail comprising a relatively flat conical body portion having a marginal depending flange adapted to engage over the upper end of a milk pail, said flange having bayonet slots in opposite sides thereof for interlocking engagement with the ears of the milking pail, a neck carried through o-ne side of the cover and tapering inwardly, a funnel piece removably ritting in the outer end ofY the neck and having a screen bottom, a conical trap member having an outwardly flaring Wall adapted to bind upon the inner end of the neck and provided With spaced screens in its bottom and imperforate trap portions between the screens, a iinal screen member having an upwardly Haring Wall adapted to bind over the conical trap member, and securing means carried by said neck and said final screen member for interlocking the nal screen member on the neck and over said conical trap member.

In testimony whereof We aiiiX our signa- 30 tures.
